.SH PARAMETERS
.ne 2
.na
\fB\fIch\fR \fR

Client handle returned from \fBcsx_RegisterClient\fR(9F).
.RE

.sp
.ne 2

\fB\fItu\fR \fR
.ad
.RS 8n
Pointer to a \fBtuple_t\fR structure (see \fBtuple\fR(9S)) returned by a call
to \fBcsx_GetFirstTuple\fR(9F) or \fBcsx_GetNextTuple\fR(9F).
.RE

.sp
.ne 2
.na
\fB\fIcbo\fR \fR
.ad
.RS 8n
Pointer to a \fBcistpl_byteorder_t\fR structure which contains the parsed
\fBCISTPL_BYTEORDER\fR tuple information upon return from this function.
.RE

.SH DESCRIPTION
This function parses the Byte Order tuple, \fBCISTPL_BYTEORDER\fR, into a form
usable by \fBPC \fRCard drivers.
.sp
.LP
The \fBCISTPL_BYTEORDER\fR tuple shall only appear in a partition tuple set for
a memory-like partition. It specifies two parameters: the order for multi-byte
data, and the order in which bytes map into words for 16-bit cards.
.SH STRUCTURE MEMBERS
The structure members of \fBcistpl_byteorder_t\fR are:
.sp
.in +2
.nf
uint32_t     order;     /* byte order code */
uint32_t     map;       /* byte mapping code */
.fi
